PACKING.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed May 25, 1905- Serial No. 262.143-

To all witmn it may concern.

Be it known that I, J AMES OSTRANDER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Packing, of which the following is a specification.

The object of my invention is to produce a steam or other high pressure packing which when subjected to compression by the gland of a stufling-box will materially expand transversely, the packing, however, being initially of sufficient rigidity to withstand high pressure.

The accompanying drawings illustrate my invention.

Figure 1 is atransverse section, ona greatlyenlarged scale, of a portion of packing constructed in accordance with my invention. Fig. 2 is a similar section of another form of my invention; Fig. 3, a similar section of a packing ring or gasket embodying my invention; Fig. 4, a plan of the ring shown in Fig. 8; and Fig. 5 a section, approximately full size, of the form shown in Fig. 1.

In the drawings, 10 indicates a plurality of layers of fabric, each of which has a plurality of portions transversely displaced-as, for instance, to form a plurality of connected corrugationsand 11 indicates a similar set or series of interposed sheets of pliable bindingsuch, for instance, as caoutchouc or rubber, similarly corrugatedsaid corrugations taking any desired form, as indicated in Figs. 1 and 2.

In practice the packing (illustrated in Figs. 1 and 2) will probably be made in large sheets composed of a plurality of alternately-arranged intermeshing corrugated fabric and pliable binding laminae and preferably surfaced top and bottom to an even surface with a pliable filling 12. Such a sheet will then be cut into strips approximately square in cross-section, and such strips will then be wrapped about a piston-rod or other part to be packed in the usual well-known manner. When such a packing is subjected to compression transversely to the corrugations, such compression will tend to straighten the sev-.

erallaminae, and as the corrugations in the fabric layers permit such extension the packing may be very materially expanded in a direction substantially at right angles to the direction of compression, so that in use, as the packing is worn by the moving part, the wear may be compensated by transverse expansion of the packing.

In Fig. 3 I show a packing-ring which may be made by taking sheets of fabric and binder, corrugating them with concentric ring corrugations, and building a packing with a plurality of such corrugated sheets alternately arranged. Such a packing when compressed will expand in radial lines. It should be understood that the term fabric used herein is not to be limited to a woven material, but

tions which, when subjected to compression in the direction of displacement, will tend to straighten.

3. A packingcomposed of alternately-arranged laminae of fabric and rubber, each fabric lamina having portions transversely displaced to form a plurality of corrugations.

4. A packing composed of alternately-arranged laminae of fabric and rubber, each fabric lamina having portions transversely displaced to form a plurality of corrugations, and the top and bottom laminae surfaced with a pliable filling.

5. A packing composed of alternately-arranged laminae of fabric and pliable binding, each fabric lamina having portions transversely displaced to form a plurality of corrugations, and the top and bottom laminae surfaced with a pliable filling.

6. A packing composed of a multiplicity of alternately-arranged laminae of fabric and pliable binding, each lamina having portions transversely displaced to form a plurality of corrugations and the laminae arranged with intermeshing corrugations.

7 A packing composed of a multiplicity of alternatelyarranged laminae of fabric and rubber, each lamina having portions transversely displaced to form a plurality of corrugations and the laminae arranged with intermeshing corrugations, and the top and bottom lamina surfaced with a pliable filling.

8. A packing composed of a multiplicity of alternately-arranged laminae of fabric and rubcorrugations, and the top and bottom laminae IO surfaced With a rubber filling.

In Witness whereof I have hereunto set my hand and seal, at Indianapolis; Indiana, this 20th day of May, A. D. 1905.
